My invention relates to .iiiiiiiovements in suppiypipe couplings, designed loi use iii connection with the liet :uid Cold vait/eipiii'ts of bath tubs. llwzitoiies mid the like. :uni has 'for its object to pilovifle pipes suit- ;iigfo for the purpose, ivliieli are iifiziiiggetl viti] lniiiig inout-lis iu the ends facing 'the fout-eis o1' cooks, foi* eiigxziging lle usual, gland-nuts, liy ineens of which the pipes are seeuieii iii place. .i iuitlioi olijeot is to peoviiie lead o1' simi- 20 loi' (.'ou'spi'essilile bushings or pooliirigs for sealing 'the joints between the pipes :und the cocksj the sziifii bushings ooiiipi'isiiig cone; sluiiieii puits enpzili'le of beingoompi'esseo amil. iiiolnieti to contorni to the interior oiA the eoiipliug. :mii iu one ziee of wliicii the iliseiuii'goemis of lie supply pipes nre ein imideii 'Soi' A es'eiiiuli leakage.

oi' not tlie initie-i' is per'feetly sind smoothly iii siiefi. the leiul l0 will eeotually seal the 3oz t. The feed bushing 1G being soft, as

(lei-scribed, also peri-nits the impressing and embedding ot' ilie liellsimped mouth of .the pipe 2 into outer face, and thus effectuzilly seuls tiiejoint between said pipe and the lend connection.

My fitting is extremely simple and novei mul it is also strong' und may be produced mul applied zu slight expense. The fitting will stuud considerable Wear and abuse and l not got oui; o'f order. From practical tests, my pipe coupling lisis been found to be superior and more freliable 'for effecting water iight` joints than-any other fitting of y the class lmoiviito ine. By the employment of the le bushing or pecking l0, herein shown und described, it is impossible for the mouth 3 of the supply pipe to come into Contact willi the iiietzil of the coupling 6, which luis heretofore been a fault common to the older fillings of the class. it is obvious that the ieaid bushing may be ooi'istiueteil Without the gioove 11, as slioii'u iu the modified View inlig. (i, and that, some (-liz'iugi'es or iuotiliiiwitioiis muy other wise lie murio in the 'loim and arrangement ot: ille ports, within the scope defined by the `appended claims, without departing from the spirit of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-

1. In a pipe joint, a rigid coupling having a funnel-shaped socket, a cone-shaped compressible bushing disposed in said socket, a, suppl)7 pipe having a bell mouth engaging and embedded in the end ofsaid bushing for sealing the joint between said pipe and said-coupling, and a gland-nut engaging the bell of the supply pipe and also said couplingl for drawing and holding said parts together. l

2. A pipe coupling, comprising a member having a funnel-shaped socket and screwthreads surrounding said socket, a second member having a aring mouth facing the larger end of said socket, a soft metallic packing comprising a coneshapcd ring inserted`in said socket ahead of said flaring mouth, and a gland-nut for drawing and holding said members together, and for embedding the mouth of said second member in said ring.

8. In a water suppl)v connection, a faucet, a coupling connected at one end to the faucet, the opposite end of said coupling having a funnel-shaped seat, a supply-pipe having a flaring mouth facing the said seat, and a conical bushing disposed in said scat, between the flaring mouth of said pipe and said coupling, said bushing adapted to be forced and molded into said seat having an annular groove to receive and to envelop the mouth of said pipe for sealing the joint.

el. In a bath fixture, a coupling for supporting a faucet, the said couplin piercing the bath tub and forming a con uctor for water to the said faucet, said coupling having a socket facingaway from the faucet, a supply-pipe carrying water to the said coupling, said pipe having a flaring mouth disposed in the socket in said coupling, and a bushing interposed between the mouth of said pipe and the wall of said socket, said bushing consisting of a material .capable of being pressed and molded to conform to the said socket said bushing having an annular groove to receive the mouth of the supply pipe for holding said mouth concentric to said socket.

In testimomv whereof I affix my signature in presence of two witnesses.
